Android Content Provider 游标查询

Question

我正在使用 Android 的内置内容提供程序 android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI。

现在我有

String[] sarray  = {"a" , "b" , "c" , "d"};`
String[] projection = {MediaStore.MediaColumns._ID , MediaStore.MediaColumns.DATA};
String selection = ?????? // My qestion

cursor = getContentResolver().query(uri, projection, null,
                    null , order);

那么我该如何写我的光标线，以便我选择 All BUT NOT saray FROM MediaStore.MediaColumns._ID 列。

Answer 1

试试这个：

String[] sarray  = {"a" , "b" , "c" , "d"};
    String[] projection = {MediaStore.MediaColumns._ID , MediaStore.MediaColumns.DATA};
    String selection =""+MediaStore.MediaColumns._ID+" !=? AND  "+MediaStore.MediaColumns._ID+"" +
            " !=? AND "+MediaStore.MediaColumns._ID+" !=? AND "+MediaStore.MediaColumns._ID+" !=?";

    cursor = getContentResolver().query(uri, projection, selection,
            sarray , order);
